The door releasing cam tracks 3 may be made with double inclines so as to operate regardless of the direction in which the car is approaching the pit and two star wheels l may be provided one at each side or approach to the pit, as indicated in the drawings. The car approaching the pit rides over the irst star wheel without effect, then is dumped at the pit and then rides over the second star wheel which closes the doors and permits the latching action to take place.

From the foregoing description taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be clear. Attention is called to thc tact that in mine cars some of the contents of the cars spill and it not infrequently happens that the material soon accumulates alongl the right of way until it reaches a level above that of the track rails. Where dump cars have their bottoms located below the axles this piling of debris along the right of way often causes the cars to be derailed with resulting tie-up and delay. By my construction this derailing and delay is avoided.

What I claim is:

l. In dump cars, a body having a skirt, wheels and axles over which said body is mounted, drop bottom pivoted doors mounted in the skirt above the level of the axles, latches mounted on the outside of said skirt for holding said doors closed, said skirt having slots through which portions of said latches project, means to release said latches at a given place along the right of way, means continuously tending to return said latches to the latching position, and means located between the rails at another place along the right of way for closing said doors.

2. In dump cars, a body having a skirt, wheels and axles over which said body is mounted, drop bottom pivoted doors mounted in the skirt above the level ot the axles, latches holding said doors closed, means to release said latches at a given place along the right of way, means continuously tending to return said latches to the latching position, and means located between the rails at anotherl place along the right of way for closing said doors, said closing means comprising a star wheel rotatably mounted on an axle which is located below the level of the plane of the car wheel axles and having its points projecting above the plane of the car wheel axles. l

3. In dump cars, a body having a skirt, wheels and axles over which said body is mounted, drop bottom pivoted doors mounted in the skirt above the level of the axles, latches mounted on the outside of said skirt for holding said doors closed, said skirt having slots through which portions of said latches project, means to release said latches at a given place along the right of way,

means continuously tending to return said latches to the latching position, and means located between the rails at another place along the right oit way for closing said doors, said skirt having a flange located below said latches and located below said continuously tending means to protect same from roadway obstructions.

4. In dump cars, a body having a skirt, wheels and axles over which said body is mounted, drop bottom pivoted doors mounted in the skirt above the level of the axles, latches mounted on the outside of said skirt for holding said doors closed, said skirt having slots through which portions of said latches project, means to release said latches at a given place along the right of way, means continuously tending to return said latches to the latching position, and means located between the rails at another place along the right of way for closing said doors,and means to counterbalance said doors.

5. In dump cars, a body having a skirt, wheels and axles over which said body is mounted, drop bottom pivoted doors mounted in the skirt above the level of the axles, latches holding said doors closed, means to release said latches at a given place along the right of way, means continuously tending to return said latches to the latching position, and means located between the rails at another place along the right of way for closing said doors, said closing means comprising a star wheel rotatably mounted on an axle which is located below the level of the plane of the car wheel axles and having its points projecting above the plane of the car wheel axles, and means to counterbalance said doors.

6. In dump cars, a body having a skirt, wheels and axles over which said body is mounted, drop bottom pivoted doors mounted in the skirt above the level o'f the axles, latches mounted on theoutside of said skirt for holding said doors closed, said skirt having slots through which portions of said latches project, means to release said latches at a given place along the right of way, means continuously tending to return said latches to the latching position, and means located between the rails at another place along the right of way for closing said doors, said skirt having a iiange located below said latches and located below said continuously tending means to protect same from roadway obstructions, and means to counterbalance said doors.
